Unit2Howoftendoyouexercise?
2.3Grammar
一、howoften引导的特殊疑问句
1.howoften意为"多久(一次)",它引导的特殊疑问句用来询问某动作发生的频率。
howoften通常是对一些表示频率的副词提问,如:
always,usually,often,sometimes,never等,也可以对表示"多久几次"之类的频率短语提问,如onceaweek,twiceayear,threetimesaday等。
☞—Howoftendoyougobackhome?
你多久回家一次?
—Onceaweek/Often/Sometimes.一周一次/经常/有时。
2.特别提示:
若仅对像once,twice,threetimes这样只表示次数的词语提问,要用howmanytimes"多少次",不用howoften。
☞—HowmanytimeshaveyoubeentoBeijing?
你去过北京多少次?
—Onlyonce.仅仅一次。
3.注意howoften与其他短语的区别
(1)howlong主要用来提问动作延续了多长时间,答语通常含有"for+一段时间"、"since+时间点"或since引导的时间状语从句。
问句和答语中的谓语动词通常为延续性动词。
howlong也可以用来询问长度。
☞—HowlongcanIkeepthisbook?
这本书我能借多长时间?
—Fortwoweeks.两周。
☞—Howlongisthebridge?
这座桥有多长?
—About1,000meters.大约1,000米。
(2)howsoon用来询问"过多久"动作才发生,谓语动词常为终止性动词,时态多为将来时,答语通常为"in+一段时间"。
☞—Howsoonwillyougethere?
你还有多久能到这里?
—Infiveminutes.五分钟以后。
(3)howfar用来询问两地之间的距离"有多远"。
☞—Howfarisitfromyourhometoyourfactory?
你家离你的工厂有多远?
—Abouttwentyminutes’walk.步行大约20分钟。
—______________doesyourfathergotothefitnesscenter?
—Heexercisestheretwiceaweek.
A.Howsoon B.HowoftenC.Howlong
二、"比较法"学习频率副词
相同点
always,usually,often,sometimes,hardlyever,never都是频率副词,句中只有一个行为动词时,应位于动词之前;当有助动词、系动词、情态动词时,位于其后;谓语动词为多个时,放在第一个助动词或情态动词之后(有not时,放not之后)。
always
(100%)
(1)always表示动作重复,状态连续,中间从来没有间断,表示频率最大,意思是"总是,一直,永远"。
其反义词为never。
(2)always与进行时态连用,并不强调动作正在进行,而是表示说话人的"赞叹、不满、厌烦"等情绪,带有强烈的感情色彩,结构:
bealwaysdoingsth。
☞Sheisalwaysaskingforleave.她老是请假。
(表示不满)
(3)always与not连用,表示部分否定,意思是"不总是"。
☞Thericharenotalwayshappy.有钱人未必总幸福。
☞Idonotalwaysbelievewhathesays.我并没始终相信他所说的话。
usually
(80%左右)
usually的频率仅次于always,意为"通常",表示通常如此,很少例外。
其反义词为unusually。
usually一般情况下位于句中。
☞Heusuallygoestobedatteno’clock.他通常在10点睡觉。
☞WhatdoyouusuallydoonSundays?
你通常星期天干什么?
often
(50%左右)
often"经常,常常",强调经常性,表示动作重复,中间有间断,它比always,usually语气弱,其反义词为seldom。
☞Theyoftengoforawalkaftersupper.晚饭后,他们常常去散步。
☞Sheisoftenlateforwork.她上班常迟到。
sometimes
(30%左右)
(1)sometimes表示"有时,不时,间或",同义词组为attimes,表示动作偶尔发生,中间间隔较大,频率比often小。
(2)sometimes有时为了对比或强调,也可位于句首或句末,但不引起倒装。
☞Sometimeshesleptathome,sometimeshesleptintheoffice.他有时在家睡觉,有时在办公室睡觉。
hardlyever
(1%-10%左右)
(1)hardlyever"几乎从不,很少",所表示的频率已经很少了,相当于seldom。
☞Hehardlyevergoestobedbeforemidnight.他很少在半夜前就寝。
(2)hardlyever是具有否定意义的副词,不与not连用。
never(0%)
(1)never表示"从来不,未曾,永不",频率为零,表示动作或状态从没发生。
(2)通常情况下,句子中用了never,就不再用含有否定意义的not,no,nothing等词。
(3)never位于句首时要用倒装语序。
☞NeverhaveImetsuchastrangeperson.我从来没有碰见过这么怪的人。
小提示
(1)表示频率的答语有everyday,onceaweek,threetimesaday等。
(2)对表示频率的副词和短语提问用howoften。
